Embodiment 1

[0079] Such as Figure 1-9 As shown, an intelligent IoT gateway for industrial sites includes an industrial PC and a dual system consisting of a main system and a real-time system established on the industrial PC. Its communication interfaces include Ethernet interfaces, POWERLINK interfaces, USB interfaces and Serial port, supporting OPC / OPC UA protocol, MODBUS TCP protocol, TCP / IP protocol to communicate with external devices.

[0080] When the gateway is working, run the main system first. After the main system is started, start the real-time system through the running tool. The real-time system occupies a core of the gateway CPU to ensure that the real-time system operates as a master station PLC, and the real-time system realizes data collection from the slave station PLC. and control; the operation of the main system ensures the normal function of the gateway. The gateway provides OPC / OPC UA interface services to realize multi-protocol analysis and unified output. The co...

Embodiment 2

[0133] An intelligent Internet of Things gateway for industrial sites, including an industrial PC, which is provided with an Ethernet interface, a POWERLINK interface, a USB interface, and a serial port, and the industrial PC also uses the OPC / OPC UA protocol, MODBUS TCP protocol, TCP / The IP protocol communicates with external devices.

[0134] With the development of the economy and the increase of labor costs, manufacturing companies are increasingly inclined to replace or reduce human work with automated and intelligent equipment or systems. However, to truly realize less people and no one in the production process, the production process management and control system needs to have the functions of collaborative control of production links such as on-site processing, handling, guarantee, and testing, real-time monitoring of on-site status, and timely response and elimination of on-site abnormalities. The industrial field intelligent IoT gateway can realize real-time collec...

Embodiment 3

[0148] A multi-protocol analysis method for intelligent IoT gateways facing industrial sites. On an industrial PC, a main system is run. After the main system is started, a real-time system is started through a running tool, and the real-time system occupies a core of the CPU of the industrial PC. , to ensure that the industrial PC operates as a PLC, and the real-time system realizes PLC data acquisition and control; the main system runs to ensure the normal function of the PC, and the industrial PC provides OPC / OPC UA interface services through the real-time system and the main system, and provides OPC / OPC UA interface services The method includes the following steps in order:

[0149] A. Establish a device description table. The device description table includes the device name, connection location, protocol type and description of each data; establish a protocol analysis stack. The protocol analysis stack is composed of various protocol analysis modules, and each protocol an...

Abstract

The invention discloses an industrial field oriented intelligent Internet-of-things gateway which comprises an industrial PC. The industrial PC is provided with an Ethernet interface, a POWERLINK interface, a USB interface and a serial port. The industrial PC performs communication with external equipment through an OPC / OPC UA protocol. Along with economy development and manpower cost increase, amanufacturing enterprise tends to utilize automatic and intelligent equipment or system for replacing or reducing working of the man. But for truly realizing few man working and no-man working in a production process, cooperated control of producing steps of production field processing, conveying, ensuring, detecting and the like is required in a production process control system. Furthermore functions such as real-time monitoring of a field state and in-time response elimination of a field abnormity are required. The industrial field oriented intelligent Internet-of-things gateway can realizereal-time acquisition of field data, intelligent perception and real-time optimization control of the process. Furthermore the industrial field oriented intelligent Internet-of-things gateway can supply basic supporting for realizing a production process intelligent control function.

Description

technical field [0001] The invention relates to a gateway, in particular to an intelligent IoT gateway for industrial sites. Background technique [0002] In the social environment of intelligent manufacturing, the intelligent manufacturing with CPS as the core proposed by Germany is based on the high automation and standardization of the manufacturing process. The manufacturing Internet in the United States is based on a stable and reliable network that runs through the manufacturing process. "Made in China 2025" Based on the weak foundation and uneven conditions of my country's manufacturing industry, the development focus of "integration of industrialization and industrialization" is proposed. [0003] Unavailable industrial site data and opaque processes have led to difficulties in production organization and coordination, low control efficiency, and lagging decision-making, which have become the most prominent "pain points" in the manufacturing industry and urgently need...
